Early Morning Ponderings : The Nature of Colour

[GuyOnTilt]

So once again I woke up early, and once again that led to me feeling fresher and having more mental energy in me. [img]/images/graemlins/smile.gif[/img]

So a thought just popped into my head re: colour. We all have learned thanks to Locke that colour is not a primary quality of any object, but rather a secondary characteristic that is more a product of it's primary qualities. What I'm curious about is whether these specific things we call "colours" exist out there in nature, or are they more a construct of our brains? I'm having a hard time phrasing the exact question I'm wonder about, but in essence, does colour really "exist" in the universe? I suppose this might end up pertaining to the nature of light more than anything else, something which I know relatively nothing about. My question might be better rephrased as, "Is colour an intrinsic property of light," but I'm not sure.
